-Cloaking level 4+ works as you would expect, it gives +3 seconds of cloak for each level, and it is possible to make custom graphics for these levels
-Artillery level 4 makes the cooldown time even lower, level 5 makes the cooldown time instant, but you must continually toggle it between level 4 & 5 or the weapon wont fire
There are problems with a level 3+ battery. If the total reactor power goes over 30, you will crash if something "limits" the reactor, like an ion storm or combat augs. A hacked battery also limits the reactor, but you wouldn't have the extra power to pass 30, so that isn't really an issue.
Cloaking should be 5 seconds per level, not 3. Last I checked, custom UI graphics for these aren't fully functional. The vanilla game comes with level 4 graphics, but it fails to use some of them and instead uses the level 3 graphics.
You've got you artillery levels messed up. You mean 5 and 6, not 4 and 5.
